Nocturnal high-def Los Angeles in the early to mid ’40s…Gilda, The Outlaw, The Letter on theatre marquees. Hat stores, fur stores, Atlantic Richfield gas stations. A large spotlight mounted on a flatbed truck. Hundreds upon hundreds of mid ’40s autos parked curbside — a 2021 film set in this era couldn’t hope to deliver this kind of authentic realism. Downtown Los Angeles plus the mean streets of Hollywood. Video-like clarity plus simulated sound…fairly amazing.
